Walsh and Jones both tweeted apologies.
Choosing to finally leave Seann, she continued with a plea to all women who are in similar relationships to her, 'This whole business has served to remind me that I am a strong, capable person who is now free; and no victim. "They apologised on social media and I'm sure in private to all the partners involved, so I can't really understand why the subject was brought up on It Takes Two".
At one stage, Katya and Seann stood on one side, while Neil waited on the other.
Rebecca, an actor who has been in a relationship with Seann (or 'Sean [n]' as she hilariously refers to him) for five years, released a statement via Twitter accusing him of gaslighting her.
'Strictly Come Dancing' continues on Sunday at 7.45pm on BBC One.
Both Katya and Seann issued a statement after they were caught kissing, claiming it was a "one-off mistake", with Katya insisting she was "very happy" with Neil.
Seann then added in his own message: "In light of the story in today's newspaper I would like to offer my honest apologies for my actions".
She is reportedly yet to receive a first-hand apology, said she has left him and taken the cat and is "not sorry" for doing so.
"I think what's changed in our society is that we've been fed a lie, and that's that sex is important, and sex is the thing that has the most meaning". "As he had done countless times throughout our relationship when I've questioned his inappropriate, hurtful behaviour".
There was a quick kiss on the cheek for Katya from Seann after they scored a rather generous 28 points from the judges, including an eight from Shirley who was adamant this week that she would be marking them on their dancing not their personal lives.
It had energy and was entertaining but I could sense the nerves from both of them with Katya almost tripping at the beginning and a few very nervy moments in the lifts.
Reflecting on his separation, he added: 'I made a mistake, which I'm very sorry for - sorry for the hurt that I've caused.
Tell some very close friends who, if they're anything like my wonderful network, will swoop in and take care of the logistics and of you.
"Show people, 'OK, this is what I did, I've been employed to do this job, I'm going get on with it and do it professionally'".
